"Saat ini dunia sedang dilanda wabah penyakit Coronavirus Disease (Covid-19). Hal itu mengakibatkan sebagian besar aktivitas dilakukan secara jarak jauh, salah satunya aktivitas pembelajaran. Keberadaan e-learning khususnya Learning Management System (LMS) diharapkan dapat menjadi solusi untuk kebutuhan akan pembelajaran jarak jauh. Salah satu fitur utama LMS adalah forum diskusi online. Hasil observasi terhadap aktivitas diskusi pada beberapa kelas di SCeLE Fasilkom Universitas Indonesia (UI), salah satu LMS yang dimiliki oleh UI, menunjukkan bahwa keterlibatan mahasiswa dalam forum diskusi online masih cukup rendah. Masalah terkait rendahnya keterlibatan mahasiswa dalam diskusi online ternyata juga masih menjadi tantangan bagi para pengajar. Perancangan dan analisis pengaruh gamifikasi yang direpresentasikan oleh elemen game berupa badge dan reaction system (like) terhadap keterlibatan mahasiswa dalam diskusi online pada dilakukan pada penelitian ini. Sebanyak 60 mahasiswa UI tergabung dalam penelitian ini. Aktivitas diskusi online dilakukan oleh seluruh partisipan pada aplikasi Dummy Scele (nongamifkasi) selama tiga hari dan gDummy Scele (gamifikasi) selama tiga hari berikutnya disertai dengan pengisian kuesioner pada saat berakhirnya masing-masing sesi diskusi tersebut. Hasil penelitian ini menunjukkan bahwa penerapan gamifikasi hanya berpengaruh secara signifikan terhadap jumlah reply dan skor perceived relatedness dalam diskusi online.

The world is suffering from Coronavirus Disease (Covid-19). That resulted in the majority of activities carried out remotely, one of them is learning activities. The existence of e-learning, especially Learning Management System (LMS) is expected to be a solution for the need of distance learning. One of the key features of LMS is an online discussion forum. The results of the observations of discussion activities in several classes at SCeLE Fasilkom Universitas Indonesia (UI), one of the LMS owned by UI, shows that the students engagement in online discussion forums is still quite low. Problems related to the low of student engagement in online discussions turned out to be still a challenge for educators. The design and analysis of the impact of gamification represented by game elements in the form of badges and reaction system on student engagement in online discussion was carried out in this study. Participants consisting of 60 UI students joined in this study. Online discussion activities were carried out by all participants in Dummy Scele (not gamified) for three days and gDummy Scele (gamified) for the next three days accompanied by questionnaires to be filled at the end of each discussion session. The results of this study indicate that the implementation of gamification only significantly influences the number of replies and perceived relatedness scores in online discussions. "

"Prosedur kateterisasi jantung berkaitan erat dengan penggunaan teknik fluoroskopi dalam waktu relatif lama. Dalam penelitian ini dilakukan analisa dosis radiasi personel kateterisasi jantung berdasarkan koleksi data hasil pantauan berkala Balai Pengamanan Fasilitas Kesehatan Jakarta dari berbagai rumah sakit. Untuk verifikasi, dilakukan pengukuran dosis personel kateterisasi jantung selama berlangsung prosedur Coronary Angiography dan Percutaneous Coronary Intervention. Setiap personil menggunakan 4 dosimeter, 2 film badge dan 2 TLD badge, dimana 1 film badge dan 1 TLD badge diletakkan di bawah apron sedangkan yang lain berada di luar apron dekat leher. Dari koleksi data diperoleh informasi dosis personel pengguna film badge per tahun pada umumnya berada dalam rentang (0,10–10) mSv untuk dokter, (0,10–7,20) mSv untuk perawat, dan (0,10–1,30) mSv untuk radiografer. Adapun dosis personel pengguna TLD badge per tahun tercatat (0,01–14) mSv untuk dokter, (0,01–14,50) mSv untuk perawat dan (0,01–2,50) mSv untuk radiografer. Dari hasil pengukuran di 3 rumah sakit diperoleh estimasi dosis efektif per tahun tertinggi dokter dalam rentang (4,96–8,71) mSv, perawat dalam rentang (7,51–37,34) mSv dan radiografer dalam rentang (7,40–25,32) mSv. Hasil pengukuran menunjukkan para personel kateterisasi jantung berpotensi menerima dosis tinggi, dapat melebihi nilai batas dosis sebesar 20 mSv/tahun.

Cardiac catheterization procedures were closely related to the use of fluoroscopy techniques in a relatively long time. In this study, radiation dose analysis for cardiac catheterization personnel was carried out based on data collected from the results of periodic monitoring of the Jakarta Health Facility Security Center from various hospitals. For verification, dose measurements of cardiac catheterization personnel were performed during the Coronary Angiography and Percutaneous Coronary Intervention procedures. Each personnel used 4 dosimeters, 2 film badges, and 2 TLD badges, where 1 film badge and 1 TLD badge were placed under the apron while the others were outside the apron near the neck. From the data collection, information on the dose of personnel using the film badge per year was generally in the range (0.10–10) mSv for doctors, (0.10–7.20) mSv for nurses, and (0.10–1.30 ) mSv for radiographers. The dose of personnel using the TLD badge per year was recorded (0.01–14) mSv for doctors, (0.01–14.50) mSv for nurses, and (0.01–2.50) mSv for radiographers. From the results of measurements in 3 hospitals, the highest estimated effective dose per year was doctors in the range (4.96–8.71) mSv, nurses in the range (7.51–37.34) mSv, and radiographers in the range (7.40– 25.32) mSv. The measurement results show that cardiac catheterization personnel had the potential to receive high doses, which can exceed the dose limit value of 20 mSv/year."

"Instrumen pemantauan dosis radiasi sinar-x untuk para pekerja radiasi berhasil dikembangkan. Instrumen ini dapat mengukur densitas dan dosis radiasi yang direkam oleh film badge yang dikenakan oleh para pekerja radiasi. Sistem instrumentasi dirancang menggunakan sensor cahaya, DAQ, dan PC dengan menggunakan perangkat lunak LabVIEW. Film badge yang digunakan mempunyai tiga jenis filter yaitu Plastik, SnPb dan Dural. Sensor cahaya yang dipakai mempunyai kemampuan deteksi antara 5-500 lux. Data atenuasi intensitas cahaya oleh film badge yang dideteksi oleh sensor cahaya dirubah ke digital dan diolah oleh DAQ. Data ini kemudian dianalisis dan disimpan di data based beserta identitas pekerja, densitas film, dosis radiasi, dan waktu pengukuran. Data dapat diakumulasi sehingga riwayat paparan radiasi dari pekerja dapat dimonitor dan tersimpan dengan baik. Kalibrasi instrument dilakukan dengan menggunakan kalibrator film densitas. Hasil pengukuran densitas film kalibrator sudah mendekati nilai densitas yang sudah disertifikasi. Instrumen ini dapat dioperasikan dan menunjukkan hasil ukur secara langsung yang dapat dimonitor melalui GUI yang dirancang secara interaktif.

The instrument monitoring radiation doses for the workers in a radiology department at the hospital have been successfully developed. These instruments could measuring density and the radiation doses recorded by film badges worn by radiation workers. Instrumentation system is designed using a light sensors, DAQ, and a PC by LabVIEW software. Film badges that are used had three types of filters ie Plastics, SnPb and Dural. The light sensor has a detection capabilities used between 500-500 lux. A data attenuation of light intensities by film badge detected by light sensors to digital converted and processed by DAQ. This data is then analyzed and stored in a data-based workers and their identity, the film density, radiation doses, and time measurement. The data can be accumulated so that a history of radiation exposure from workers could be monitored and saved fine. The instrument calibration performed using film density calibrator. This instrument can operate and shows the results of direct measurement that can be monitored via a GUI that is designed interactively."
